Products / Parker / Seal and O-Rings / Symmetrical Rod And Piston Seal Praedifa Series TA, Ultrathan®
Rod seal for hydraulic cylinders, single-acting, polyurethane compact PARK-O-PAK® design. For high-pressure applications. Robust seal profile for harsh operating conditions. Long axial assembly length.
The PARK-O-PAK® rod seal TA made of
wear-resistant Ultrathan® is a compact seal design for hydraulic
applications. Due to its symmetric design, the seal can also be used
as a piston seal.
The O-ring guarantees the pre-loading of the seal lips, even under
low pressures or vacuum. Due to the good setting behavior of the
elastomer O-ring, this pre-loading is largely constant. As system
pressure increases, compression of the sealing edges rises due to
the pressure-dependent deformation of the seal profile.
There are three variants of the PARK-O-PAK® product series. The
product series BA is suitable for standard grooves, e.g. according
to ISO 5597. The product series SA is suitable for axially short
compact designs. The product series TA is suitable for radially slim
designs, e.g. for telescopic cylinders.
